“…Where you can see graphically the interpretation of the results that adding potato husk ash by 20% improves its CBR with respect to the other additions of 10% and 15% taking as reference the standard of
Mexico which shows that it is the only one that meets these parameters where it could be said that adding potato husk ash by 20% is optimal, since with this addition we obtain a CBR greater than 20% in the 6 calicatas and its liquid limits in the 6 calicatas do not exceed the value of 40 as the plasticity index does not exceed the value of 12 that are the parameters of the standard of
Mexico, complying at the same time with the Peruvian regulations that indicate that for an optimal subgrade, the CBR must be ≥ 6%, in the Peruvian regulations according to the Ministry of Transport and Communications (MTC), "Manual of Roads: Soils, Geology, Geotechnics and Pavements" (Manual de Carreteras & MTC, 2014, p. 40) recommends stabilizing or changing for another material.…”
